The Accelerated Weathering Test Chamber is a high-precision instrument designed to simulate outdoor climatic conditions—such as solar radiation, temperature, humidity, and rainfall—in a controlled laboratory environment. It enables rapid assessment of the weather resistance and long-term reliability of materials and products.
| Name | Accelerated Weathering Test Chamber |
| Temperature range(℃) | -40~+100 |
Humidity range (%R.H) | 20~90 |
| Temperature deviation (°C) | ≤±2.0 |
| Temperature uniformity (°C) | ≤4 |
| Temperature fluctuation (℃) | ≤±2.0 |
Humidity fluctuation (%RH) | ≤±2.0 |
| Heating/Cooling Rate | -40℃ to +85°C | Rate of Change: ≥2°C/min，Acceptance of the temperature variation rate shall be in accordance with IEC 60068-3-5. |
| Spectral Range | 280nm~3000nm |
| Spectral Characteristics | For irradiance levels between 2000 W/m² and 3100 W/m², the light source shall meet or exceed the IEC 60904-9 Class BBA rating (covering spectral match, irradiance uniformity, and spectral stability). For irradiance levels between 1000 W/m² and 2000 W/m², the light source shall meet or exceed the IEC 60904-9 Class CBA rating. |
